Artikeltext hochladen : AMG GT 63 downpipes, what are the benefits of the Brondex catless or catted GT63 downpipes for Mercedes AMG GT 63 S X290?

Upgrading the downpipes on a Mercedes AMG GT 63 downpipes can provide several benefits, and the choice between catless or catted downpipes from a manufacturer like Brondex can significantly influence these outcomes. Here’s a breakdown of the

AMG GT 63 Catless Downpipes

Performance Increase:

  • Horsepower and Torque: Catless downpipes typically offer the greatest increase in horsepower and torque. This is because they remove the restrictive catalytic converters, allowing for better exhaust flow and reducing backpressure.
  • Turbo Efficiency: Improved exhaust flow can help the turbochargers spool faster, enhancing throttle response and reducing turbo lag.

Sound Enhancement:

  • Aggressive Exhaust Note: Without catalytic converters, the exhaust sound becomes louder and more aggressive. This can be a desirable feature for enthusiasts looking for a more race-inspired exhaust note.
    Weight Reduction:
  • Lighter Components: Catless downpipes are generally lighter than their catted counterparts, which can contribute to a slight reduction in overall vehicle weight.

GT63 Catted Downpipes

Performance Increase:

  • Balanced Gains: While not as significant as catless downpipes, catted downpipes still provide a noticeable improvement in horsepower and torque over stock components due to higher flow catalytic converters.
  • Emission Control: High-flow cats balance performance gains with emission control, making them a good compromise between power and legality.

Sound Enhancement

  • Refined Exhaust Note: Catted downpipes can still enhance the exhaust sound, making it deeper and sportier without being overly loud or raspy. This can appeal to those who want an improved sound without drawing too much attention.

Emission Compliance

  • Legal Compliance: Catted downpipes are more likely to pass emissions tests and be street legal in more regions compared to catless downpipes. This makes them a more practical option for daily drivers who want performance gains without the risk of legal issues.

Heat Management

  • Reduced Cabin Heat: Catalytic converters can help manage exhaust temperatures better, potentially reducing the heat radiated into the cabin area.


  • Catless Downpipes: Offer maximum performance gains and the most aggressive sound but come with the trade-offs of increased emissions, potential legal issues, and possibly more cabin heat.
  • Catted Downpipes: Provide a good balance between performance and compliance with emissions regulations, offering a sporty yet refined exhaust note without the risks associated with catless options.

Choosing between catless and catted downpipes ultimately depends on your performance goals, sound preferences, and local emissions regulations. For track-focused builds or areas with lenient emissions laws, catless downpipes might be preferable. For daily driving and a more balanced approach, catted downpipes offer a practical solution.
